Notifications of action items in messages

ABSTRACT

In some implementations, a method includes extracting completion criteria of an action item and parameters of the completion criteria from a message portion of a user message between users. In response to determining, from sensor data provided by one or more sensors associated with a user, the user practices a routine; a routine-related aspect is generated from a user routine model of the user for the routine. In is inferred at least one of the extracted completion criteria of the action item is unsatisfied based on the extracted parameters and the identified routine-related aspect. Based on the inferring, a notification is provided to at least one user associated with the action item.

CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. Non-Provisional application Ser. No. 15/623,300, titled “NOTIFICATIONS OF ACTION ITEMS IN MESSAGES”, filed Jun. 14, 2017, which claims the benefit of U.S. Provisional Application No. 62/397,680, titled NOTIFICATIONS OF ACTION ITEMS IN MESSAGES, filed Sep. 21, 2016, both of which are hereby expressly incorporated by reference in its entirety.

BACKGROUND

Computer messaging technologies, such as Email or instant messaging, allow computer messages, or user messages, to be exchanged between users. Often, it is desirable for a user to respond to a computer message. For example, an email may include a request that its recipients provide a response to the email, and can specify particular information to include in the response or other criteria to satisfy the request. However, many users have difficultly tracking which emails have been responded to, which emails still need some response to satisfy requests, and prioritizing responses to the emails. For example, a user may have sent many requests out to recipients and some requests may have been satisfied while others remain pending. As another example, the user may have received many requests and only responded to some. Further, in some cases, a request may be partially satisfied, but an additional response is required to fully satisfy the request.

Conventional technologies allow users to manually flag emails to assist in tracking which need a response. However, the user must both manually set and unset these flags, so they are not definitive of whether a request has been satisfied. Furthermore, these flags provide no distinction between partially and fully satisfied requests with respect to a user. Many users rely on whether an email is marked as opened or unopened to determine which emails may need a response. However, often, users open an email without reading its contents or read the email briefly, such as on a mobile phone while driving. These emails are marked as opened while they still may require some action from the user. Thus, the user must search through and read emails to discover emails that require responses, which reduces user efficiency and wastes computing resources. Additionally, users waste storage and bandwidth on follow up messages for missing or incomplete requests.

SUMMARY

This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used in isolation as an aid in determining the scope of the claimed subject matter.

Implementations of the present disclosure are directed towards systems and methods for providing automatic notifications to users based on action items determined from user messages between users. In some respects, user messages, such as emails, which are sent by a user or received by the user, are analyzed and tracked. Action items, completion criteria of the action items, and parameters of the completion criteria are extracted from at least the message portion of the user messages. The parameters can include due dates, users, and aspects used to determine whether completion criteria of action items have been satisfied. Notifications of action items are provided to users regarding the action items. The notifications can be reminders of any of the action items associated with a user. In some cases, notifications are provided for action item based on based on determining at least some completion criteria of the action items has not been satisfied. This determination can be inferred by analyzing completion criteria with respect to routine-related aspects of known routines of users.

In further respects, the system can determine and track whether completion criteria has been satisfied for various action items, and update the completion criteria for action items, as well as the determinations on whether they have been satisfied by analyzing additional information, such as additional user messages, interaction data from users, and information ingested into the system subsequent to the determinations.

In further respects, action items can be grouped together based on shared parameters of completion criteria, message attributes of user messages corresponding to the action items, category or type of completion criteria, or other similarities determined and/or identified by the system. Grouped action items can be provided to a user in a common notification, such as by transmitting a single notification corresponding to each of the action items.

DETAILED DESCRIPTION

The subject matter of aspects of the invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” may be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described.

Various aspects of the technology described herein are generally directed towards systems, methods, and computer storage media for, among other things, analyzing and tracking user messages, such as emails, with respect to users for determining notifications or other actions to take with respect to the user messages. In doing so, the systems described herein can leverage inferred aspects related to a specific user's behavior patterns, or routines, using a routine model for the user based, at least in part, on sensor data reflecting user activity as detected by one or more sensors (“interaction data”). As used herein, “user routine models” are probabilistic, machine learning constructs that infer or predict routine-related aspects associated with a specific user's behavior patterns (“routine-related aspects”) by evaluating features, attributes, or variables (“routine-related features”) according to rules, frameworks, or machine learning algorithms (“routine-related logic”) that define logical relationships amongst routine-related features or between routine-related features and routine-related inferences. In some implementations, routine-related logic further defines procedures, processes, or operations used to determine the various metrics, scores, or values associated with routine-related inferences, such as confidence scores, variance metrics, central tendency values, probability distribution functions, and the like.

“Routine-related inferences,” as used herein, describe inferences, estimations, or approximations that provide additional insight into the specific user's behavior or behavior patterns, such as with respect to interactions patterns with user messages or interactions with user messages. As such, routine-related inferences enable identification of one or more routine-related aspects that more closely reflect what the specific user's behavior will likely be at a future time. Routine-related inferences are determined by evaluating (or analyzing) one or more routine-related features derived from data associated with currently-sensed and/or historically-sensed interaction data with user routine models trained using data associated with previously-sensed interaction data. In some implementations, routine-related inferences are used to generate or update routine-related profiles associated with a specific user in order to provide time-sensitive recommendations, or notifications, personalized to the specific user's behavior pattern.

The term “service” is used broadly herein to refer to any suitable application or automation technology which may be implemented as one or more computer applications, services, or routines, such as an app running on a mobile device or the cloud, as further described herein. Similarly, the term “recommendation” is used broadly herein to refer to any recommendations, features, actions, operations, notifications, functions, and/or other utilities provided by services. The term “logic” encompasses any physical and tangible functionality for performing a task. For instance, each operation illustrated in the flowcharts may correspond to a logic component for performing that operation. An operation can be performed using, for instance, software running on computer equipment, hardware (e.g., chip-implemented logic functionality), etc., and/or any combination thereof. When implemented by computing equipment a logic component represents an electrical component that is a physical part of the computing system, however implemented.

Implementations of the present disclosure are directed towards systems and methods for providing automatic notifications to users based on action items determined from user messages between users. In some respects, user messages, such as emails, which are sent by a user and received by the user, are analyzed and tracked. Action items, completion criteria of the action items, and parameters of the completion criteria are extracted from at least the message portion of the user messages. The parameters can include due dates, users, and aspects used to determine whether completion criteria has been satisfied. Notifications of action items are provided to users regarding the action items. The notifications can be reminders of any of the action items associated with a user. In some cases, notifications are provided for action item based on based on determining at least some completion criteria of the action items has not been satisfied. This determination can be inferred by analyzing completion criteria with respect to routine-related aspects of known routines of users.

In further respects, the system can determine and track whether completion criteria has been satisfied for various action items, and update the completion criteria for action items, as well as the determinations on whether they have been satisfied by analyzing additional information, such as additional user messages, interaction data from users, and information ingested into the system subsequent to the determinations.

In further respects, action items can be grouped together based on shared parameters of completion criteria, message attributes of user messages corresponding to the action items, category or type of completion criteria, or other similarities determined and/or identified by the system. Grouped action items can be provided to a user in a common notification, such as by transmitting a single notification corresponding to each of the action items.

In some respects, the present disclosure provides for significant reductions to utilization of computing resources, such as bandwidth and storage, as well as improvement to user efficiency in interacting with user messages, such as emails, presented to users. For example, conventional technologies do not track which user messages need a response or provide a distinction between partially and fully satisfied requests with respect to a user. By extracting completion criteria of action items from user messages and determining whether to notify users of the action items and/or when to notify users of the action items, users need not search through user messages for those that still require a response. Furthermore, users need not meticulously flag and un-flag user messages to track their response status. Thus, users are able to more accurately identify action items that need responses while reducing the effort exerted by the user with input devices. Additionally, storage and bandwidth are preserved by avoiding follow up messages for missing or incomplete action items. Determinations and inferences of whether completion criteria are satisfied are enhanced by factoring in user knowledge about which routines users practice, and leveraging routine-related aspects of those routines, so as to further improve user efficiency and reduce computer response consumption. As the system learns more about the user, such as which routines users practice and routine-related aspects of those routines, these inferences can be updates to define previous determinations and facilitates more accurate notifications on action items.

It should be understood that operating environment 100 shown in FIG. 1 is an example of one suitable operating environment. Each of the components shown in FIG. 1 may be implemented via any type of computing device, such as computing device 600, described in connection to FIG. 6, for example.

It should be understood that any number of user devices, servers, and data sources may be employed within operating environment 100 within the scope of the present disclosure. Each may comprise a single device or multiple devices cooperating in a distributed environment. For instance, server 106 may be provided via multiple devices arranged in a distributed environment that collectively provide the functionality described herein. Additionally, other components not shown may also be included within the distributed environment.

User devices 102 a and 102 b through 102 n can be client devices on the client-side of operating environment 100, while server 106 can be on the server-side of operating environment 100. Server 106 can comprise server-side software designed to work in conjunction with client-side software on user devices 102 a and 102 b through 102 n so as to implement any combination of the features and functionalities discussed in the present disclosure. This division of operating environment 100 is provided to illustrate one example of a suitable environment, and there is no requirement for each implementation that any combination of server 106 and user devices 102 a and 102 b through 102 n remain as separate entities.

(For example, in one implementation, one or more data sources 104 a through 104 n provide (or make available for access) user data to data collection component 215 of FIG. 2.) At least one of Data sources 104 a and 104 b through 104 n may be discrete from user devices 102 a and 102 b through 102 n and server 106 or may be incorporated and/or integrated into at least one of those components. In one implementation, one or more of data sources 104 a though 104 n comprises one or more sensors, which may be integrated into or associated with one or more of the user device(s) 102 a, 102 b, or 102 n or server 106. Examples of sensed user data made available by data sources 104 a though 104 n are described further in connection to data collection component 215 of FIG. 2.

Turning now to FIG. 1, a block diagram is provided showing an example operating environment 100 in which some embodiments of the present disclosure may be employed. It should be understood that this and other arrangements described herein are set forth only as examples. Other arrangements and elements (e.g., machines, interfaces, functions, orders, and groupings of functions, etc.) can be used in addition to or instead of those shown, and some elements may be omitted altogether for the sake of clarity. Further, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, and in any suitable combination and location. Various functions described herein as being performed by one or more entities may be carried out by hardware, firmware, and/or software. For instance, some functions may be carried out by a processor executing instructions stored in memory.

Among other components not shown, example operating environment 100 includes a number of user devices, such as user devices 102 a and 102 b through 102 n; a number of data sources, such as data sources 104 a and 104 b through 104 n; server 106; sensors 103 and 107, and network 110. It should be understood that environment 100 shown in FIG. 1 is an example of one suitable operating environment. Each of the components shown in FIG. 1 may be implemented via any type of computing device, such as computing device 600 described in connection to FIG. 6, for example. These components may communicate with each other via network 110, which may include, without limitation, one or more local area networks (LANs) and/or wide area networks (WANs). In exemplary implementations, network 110 comprises the Internet and/or a cellular network, amongst any of a variety of possible public and/or private networks.

It should be understood that any number of user devices, servers, and data sources may be employed within operating environment 100 within the scope of the present disclosure. Each may comprise a single device or multiple devices cooperating in a distributed environment. For instance, server 106 may be provided via multiple devices arranged in a distributed environment that collectively provide the functionality described herein. Additionally, other components not shown may also be included within the distributed environment.

User devices 102 a and 102 b through 102 n may be client devices on the client-side of operating environment 100, while server 106 may be on the server-side of operating environment 100. Server 106 can comprise server-side software designed to work in conjunction with client-side software on user devices 102 a and 102 b through 102 n so as to implement any combination of the features and functionalities discussed in the present disclosure. This division of operating environment 100 is provided to illustrate one example of a suitable environment, and there is no requirement for each implementation that any combination of server 106 and user devices 102 a and 102 b through 102 n remain as separate entities.

User devices 102 a and 102 b through 102 n may comprise any type of computing device capable of being operated by a user. For example, in one embodiment, user devices 102 a through 102 n may be the type of computing device described in relation to FIG. 6 herein. By way of example and not limitation, a user device may be embodied as a personal computer (PC), a laptop computer, a mobile or mobile device, a smartphone, a tablet computer, a smart watch, a wearable computer, a personal digital assistant (PDA), an MP3 player, a global positioning system (GPS) or device, a video player, a handheld communications device, a gaming device or system, an entertainment system, a vehicle computer system, an embedded system controller, a camera, a remote control, a bar code scanner, a computerized measuring device, an appliance, a consumer electronic device, a workstation, or any combination of these delineated devices, or any other suitable device.

Data sources 104 a and 104 b through 104 n may comprise data sources and/or data systems, which are configured to make data available to any of the various constituents of operating environment 100, system 200 described in connection to FIG. 2. (For example, in one embodiment, one or more data sources 104 a through 104 n provide or make available for access user data to data collection component 215 of FIG. 2), or system 300 described in connection to FIG. 3. Data sources 104 a and 104 b through 104 n may be discrete from user devices 102 a and 102 b through 102 n and server 106 or may be incorporated and/or integrated into at least one of those components. In one embodiment, one or more of data sources 104 a though 104 n comprise one or more sensors, which may be integrated into or associated with one or more of the user device(s) 102 a, 102 b, or 102 n or server 106. Some examples of such data sources include sensor 103 or 107, described in FIG. 1. Examples of sensed user data made available by data sources 104 a though 104 n are described further in connection to data collection component 215 of FIG. 2.

Operating environment 100 can be utilized to implement one or more of the components of systems 200 and 300 later described in additional detail. This includes components for collecting user data, monitoring activity events, determining activity patterns, consuming activity pattern information to provide an improved user experience, generating personalized content, and/or presenting notifications and related content to users.

Operating environment 100 can be utilized in conjunction with the components of the exemplary computing system architecture depicted in FIG. 2 that is suitable for implementing embodiments of the invention and is generally designated as system 200. System 200 represents only one exemplary computing system architecture suitable for implementing aspects of the invention. Other arrangements and elements can be used in addition to or instead of those shown, and some elements may be omitted altogether for the sake of clarity. Further, as with operating environment 100, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components, and in any suitable combination and location. Among other components not shown, system 200 is generally comprised of components for inferring routine-related aspects for a specific user based on interaction data. System 200 includes such components as data collection component 215, storage 220, routine model engine 240, routine inference engine 250, and recommendation engine 260, all of which are communicatively coupled via network 110 or another network.

In some implementations, the functions performed by components of system 200 are associated with one or more personal assistants and/or user messaging applications, services, or routines. In particular, such applications, services, or routines may operate on one or more user devices (such as user device 102 a), servers (such as server 106), may be distributed across one or more user devices and servers, or be implemented in the cloud. Moreover, in some implementations these components of system 200 may be distributed across a network, including one or more servers (such as server 106) and client devices (such as user device 102 a), in the cloud, or may reside on a user device such as user device 102 a. As with operating environment 100, some of the components described herein may be embodied as a set of compiled computer instructions, computer functions, program modules, computer software services, or an arrangement of processes carried out on one or more computer systems, such as computing device FIG. 6 described in connection to FIG. 6.

For example, these components, functions performed by these components, or services carried out by these components may be implemented at appropriate abstraction layer(s) such as the operating system layer, application layer, hardware layer, etc., of the computing system(s). Alternatively, or in addition, the functionality of these components and/or the implementations of the invention described herein can be performed, at least in part, by one or more hardware logic components. Exemplary types of hardware logic components that can be used include Field-programmable Gate Arrays (FPGAs), Application-specific Integrated Circuits (ASICs), Application-specific Standard Products (ASSPs), System-on-a-chip systems (SOCs), Complex Programmable Logic Devices (CPLDs), etc. Additionally, although functionality is described herein with regards to specific components shown in example system 200, it is contemplated that in some implementations functionality of these components can be shared or distributed across other components.

Data collection component 215 is generally responsible for acquiring, accessing, or receiving (and in some cases also identifying) interaction data from one or more data sources, such as data sources 104 a and 104 b through 104 n of FIG. 1. For example, interaction data may be received from a plurality of user devices (such as user devices 102 a and 102 b through 102 n of FIG. 1) associated with a user or in some instances, associated with multiple users. In this way, user activity of a particular user from multiple user devices used by the user (e.g. the user's mobile phone, laptop, tablet, etc.), may be received as interaction data. In addition, interaction data may be received from a plurality of user accounts, such as social media accounts, email accounts, computer login accounts, and/or computer messaging accounts. Other examples of suitable accounts are described below with respect to user data.

Interaction data may be received, acquired, or accessed, and optionally accumulated, reformatted and/or combined, by data collection component 215 and stored in one or more data stores such as storage 220. For example, interaction data may be stored in or associated with a user profile 230, as described herein. The one or more data stores may thus be available to routine model engine 240, routine inference engine 250, and recommendation engine 260. In some implementations, data collection component 215 is configured to accumulate interaction data reflecting user activity detected by one or more sensors for an individual user (“individual-sourced interaction data”). In some implementations, data collection component 215 is configured to accumulate interaction data associated with user-source interactions for a plurality of users (“crowd-sourced interaction data”). Any personally identifying data (i.e., interaction data that specifically identifies particular users) may either not be uploaded from the one or more data sources with interaction data, not permanently stored, and/or not made available to routine model engine 240, routine inference engine 250, and/or recommendation engine 260.

Interaction data may be received from a variety of sources where the data may be available in a variety of formats. For example, in some implementations, user data accumulated by data collection component 215 is received via one or more sensors associated with user devices (such as user device 102 a and/or other devices associated with the user), servers (such as server 106), and/or other computing devices. As used herein, a sensor may include a function, routine, component, device, or combination thereof for sensing, detecting, or otherwise obtaining information such as user data from data sources (e.g., data source 104 a of FIG. 1), and may be embodied as hardware, software, or both.

By way of example and not limitation, user data may include data that is sensed or determined from one or more sensors (referred to herein as “sensor data”), such as location information of mobile device(s), smartphone data (such as phone state, charging data, date/time, or other information derived from a smartphone), user-activity information (for example: app usage; online activity; searches; voice data such as automatic speech recognition; activity logs; communications data including calls, texts, instant messages, and emails; website posts; other user-data associated with communication events; etc.) including user activity that occurs over more than one user device, user history, session logs, application data, contacts data, calendar and schedule data, notification data, social-network data, news (including popular or trending items on search engines or social networks), online gaming data, ecommerce activity (including data from online accounts such as a Microsoft® account, Amazon.com®, eBay®, PayPal®, or Xbox Live®), user-account(s) data (which may include data from user preferences or settings associated with a personal assistant application or service), home-sensor data, appliance data, global positioning system (GPS) data, vehicle signal data, traffic data, weather data (including forecasts), wearable device data, other user device data (which may include device settings, profiles, network connections such as Wi-Fi network data, or configuration data, data regarding the model number, firmware, or equipment, device pairings, such as where a user has a mobile phone paired with a Bluetooth headset, for example), gyroscope data, accelerometer data, payment or credit card usage data (which may include information from a user's PayPal account), purchase history data (such as information from a user's Amazon.com or eBay account), other sensor data that may be sensed or otherwise detected by a sensor (or other detector) component including data derived from a sensor component associated with the user (including location, motion, orientation, position, user-access, user-activity, network-access, user-device-charging, or other data that is capable of being provided by one or more sensor component), data derived based on other data (for example, location data that can be derived from Wi-Fi, Cellular network, or IP address data), and nearly any other source of data that may be sensed or determined as described herein.

In some respects, user data may be provided in user signals. A user signal can be a feed of user data from a corresponding data source. For example, a user signal could be from a smartphone, a home-sensor device, a GPS device (e.g., for location coordinates), a vehicle-sensor device, a wearable device, a user device, a gyroscope sensor, an accelerometer sensor, a calendar service, an email account, a credit card account, or other data sources. In some implementations, data collection component 215 receives or accesses data continuously, periodically, or as needed.

In general, storage 220 is configured to store computer instructions (e.g., software program instructions, routines, or services), and/or models used in implementations of the invention described herein. In some implementations, storage 220 also stores information or data received via the various components of system 200 and provides the various components of system 200 with access to that information or data. For example, storage 220 may store such information or data as interaction data, descriptive information associated with any of the user data described with respect to data collection component 215, interaction data, inferential data, interaction datasets, crowd-sourced datasets, individual-sourced datasets, user routine models, routine-related inferences, routine-related profiles, and one or more user profiles (e.g. user profiles 230). In an implementation, storage 220 comprises a data store (or computer data memory). Further, although depicted as a single data store component, storage 220 may be embodied as one or more data stores or may be in the cloud.

Exemplary user profile 230 includes information associated with a specific user, or in some implementations, a group or category of users. As shown in FIG. 2, user profiles 230 include such information as: user attribute data 231, interaction datasets 233, user routine models 235, and routine-related profiles 237. The information stored in user profiles 230 may be available to the other components of exemplary system 200.

User attribute data 231 comprises any characteristic, trait, or attribute associated with a specific user. In some implementations, user attribute data 231 includes information relating to demographic data, location data, occupational data, educational data, and the like. For example, demographic data includes such information as age, gender, nationality, religious affiliations, ethnicities, and the like. As another example, location data includes such information for the specific user as: current physical location, work location, home location, projected future location(s), and the like. In some implementations, similar location data may be available for one or more user devices or one or more individuals associated with the specific user (e.g. friends, family, etc.). User attribute data 231 may be acquired from users in a variety of ways. In some implementations, user attribute data 231 is submitted by users to system 200 (e.g., explicitly) via any of the input devices described below with respect to computing device 600 of FIG. 6. In some implementations, user attribute data 231 is compiled from user data submitted by users as part of registering for user profiles with applications; social media profile building; census registration; and the like. In some implementations, user attribute data 231 is acquired from one or more reports associated with users, such as credit reports; background reports; employment reports; and the like. In some cases, at least some of user attribute data 231 is inferred, for example, based on routine-related inferences described in additional detail below. These attributes may be referred to as routine-related aspects, or routine-related attributes.

Interaction dataset 233 broadly pertains to any dataset populated using any data associated with previously-sensed interaction data that is used to train, test, and/or validate user routine models 235. A user routine model 235 may be a machine-learned, probabilistic inference model configured to determine routine-related inferences by evaluating data associated with currently-sensed and/or historically-sensed interaction data, in some implementations. Routine-related profile 237 may include information regarding one or more routine-related aspects for a specific user. Routine-related profile 237 may be initialized and/or updated using routine-related inferences determined by evaluating currently-sensed and/or historically-sensed interaction data using user routine model 235. By way of example, for a routine related to checking email, routine-related aspects could include one or more of the following aspects of a specific user's email checking pattern: frequencies of checking email, times or time ranges of checking email, durations of checking email, frequency of responding to emails, frequent senders of emails, and the like. Routine-related aspects of routine-related profile 237 may be represented according to any known probabilistic machine learning model output. For example, routine-related aspects may be represented as a statistical distribution describing a particular aspect in terms of a central tendency metric (e.g. a mean, a median, or a mode) and a variance metric (e.g. a range, a standard deviation, or a variance). Further details regarding interaction datasets 233, user routine models 235, and routine-related profiles 237 are described below with respect to routine model engine 240.

Routine model engine 240 is generally adapted to populate interaction datasets 233 in cooperation with storage 220 and train user routine models 235 using those interaction datasets 233. User routine models 235 trained by routine model engine 240 enable routine inference engine 250 to infer (or predict) routine-related aspects for a specific user as well as various attributes of the user or data associated with the user, such as emails. As shown in exemplary system 200, routine model engine 240 includes dataset preprocessor 241, interaction dataset compiler 243, and routine model trainer 245.

Dataset preprocessor 241 may be configured to create user-attribute filters using user attribute data 231, in implementations where crowd-sourced datasets are used to populate interaction datasets 233. In these implementations, user routine models 235 may, in a sense, be pre-tailored for a specific user through selecting previously-sensed interaction data that is more relevant to the specific user for use in training user routine models. Dataset preprocessor 241 enables such pre-tailoring of user routine models 235 by applying at least one user attribute filter to crowd-sourced datasets prior to populating interaction datasets 233 with their associated previously-sensed interaction data. In some implementations, user attribute filters are based on data acquired from user attribute data 231 associated with user profiles 230. In some implementations, user attribute filters may be based on data acquired from users via any of the input devices described below with respect to computing device 600 of FIG. 6.

For example, a user-location filter may be applied to crowd-sourced datasets to exclude previously-sensed interaction data associated with users outside of a pre-determined distance range from a specific user. As another example, a user-demographic filter may be applied to crowd-sourced datasets to only include previously-sensed interaction data associated with users having at least one demographic characteristic in common with a specific user (e.g. age, income, cultural identity, gender, etc.). In another example, a user-occupation filter is applied to crowd-sourced data sets to only include previously-sensed interaction data associated with users having at least one occupational characteristic in common with a specific user (e.g. job title, industry, level of experience, etc.).

Interaction dataset compiler 243 is configured to populate, compile, or build interaction datasets 233 with previously-sensed interaction data received from data collection component 215, storage 220, and/or routine inference engine 250. In some implementations, interaction dataset 233 is populated with individual-sourced data reflecting a specific user's activity as detected by one or more sensors. In some implementations, interaction dataset 233 is populated with crowd-sourced interaction data reflecting the activity of multiple users as detected by one or more sensors. In some implementations, interaction dataset 233 is populated with descriptive data associated with previously-sensed interaction data, such as time/date stamps, metadata tags, geographical location data, etc. In some implementations, interaction dataset is populated with contextual data as discussed in more detail below with respect to inferential evaluator 253.

Implementations, routine model trainer 245 may be configured to train user routine models (e.g., User routine model 235) through analyzing interaction datasets 233 to identify routine-related features, routine-related aspects, routine-related logic, and in some implementations routine-related weights. As discussed above, in some implementations, user routine model 235 comprises a machine-learned, probabilistic inference model configured to determine routine-related inferences by evaluating data associated with currently-sensed interaction data. As such, User routine model 235 may be trained by any known machine learning technique.

Routine-related features may be identified by routine model trainer 245 based on any combination of user data described in connection to data collection component 215, descriptive information associated with such user data, and contextual data provided by inferential evaluator 253. In some implementations, routine-related features are identified by routine model trainer 245 recognizing patterns between data within interaction dataset 233 and a specific user's routine. For example, routine model trainer 245 may use a pre-determined statistical threshold, such as a correlation threshold (either positive or negative), to recognize such patterns. Pre-determined statistical thresholds may reflect relationships among identified routine-related features or between routine-related features and various aspects of the specific user's routine.

In some implementations, routine-related features utilize user signals providing a feed of interaction data from data sources (e.g. a user device) associated with a user. In these implementations, feeds of interaction data may be provided at any level of granularity including: continuously, periodically (e.g. every minute, 5 minutes, hour, 2 hours, etc.), or upon the user signal transitioning logic states (e.g. off to on, high to low, etc.). User signals providing a feed of interaction data may be received from sensors associated with applications or devices on a client-side, on a server-side, in the cloud, or any combination thereof.

Routine model trainer 245 is further configured to determine routine-related logic for user routine models that maps data associated with interaction data to routine-related features and defines logical relationships amongst routine-related features and/or between routine-related features and routine-related inferences. In some implementations, routine-related logic further define procedures, processes, or operations used to determine the various metrics, scores, or values associated with routine-related inferences, such as confidence scores, variance metrics, central tendency values, probability distribution functions, and the like.

In some implementations, confidence scores are employed to quantify a degree of confidence in how accurately one or more routine-related aspects associated with a routine-related profile reflect the user's routine. In these implementations, confidence scores may be associated with the routine-related profile overall, particular routine-related aspects of the routine-related profile, and/or one or more metrics (e.g. variance metric, central tendency metric, etc.) associated with particular routine-related aspects of the routine-related profile. Stated differently, a confidence score is an associated probability or confidence that indicates a likelihood of a predicted routine-related aspect coinciding with a user's actual routine. In some implementations, services use the confidence score in various ways, such as for a threshold in providing time-sensitive recommendations to a user.

Routine model trainer 245 may be further configured to assign at least one routine-related weight for the routine-related features in implementations where routine-related weights are used. Routine-related weights may be determined by analyzing interaction datasets 233 used to train user routine models 235. Routine-related weights reflect a corresponding routine-related feature's relative statistical significance in determining (predicting the likelihood of) a routine-related inference. Such routine-related weights may be assigned by routine model trainer 245 to one or more routine-related features associated with user routine models.

Although FIG. 2 depicts routine model engine 240 as a separate component, those skilled in the art will recognize that routine model engine 240, or any sub-component thereof, may be integrated with another component, such as an interaction data collection component, an analysis tool, a user device, a web server, or the like. In some implementations, routine model engine 240 is implemented as part of routine inference engine 250 or other components similarly designed to generate routine-related profiles. In some implementations, routine model engine 240 is implemented as part of a web server, a hybrid hardware/software component, or as a software module running on a conventional personal computer that is being used to infer routine-related aspects of user sleep patterns using interaction data.

Routine inference engine 250, in general, is configured to infer routine-related aspects by analyzing currently-sensed interaction data with user routine models trained using previously-sensed interaction data. As shown in exemplary system 200, routine inference engine 250 includes feature preprocessor 251, inferential evaluator 253, data analysis component 255, and outlier detector 257.

Feature preprocessor 251 is configured to map data associated with interaction data to generate routine-related features for analysis by data analysis component 255, as identified by routine model trainer 245. Routine-related features generated by feature preprocessor 251 may include any of the data associated with interaction data discussed herein. In some implementations, feature preprocessor 251 is further configured to convert data associated with interaction data into appropriate formats for mapping to routine-related features, as specified by routine model trainer 245. For example, data associated with interaction data may be received as analog data or digital data provided as any number of data types including: matrices; vectors; and scalars. In this example, feature preprocessor 251 converts such data into an appropriate format for corresponding routine-related features to be usable by data analysis component 255.

In some implementations, feature preprocessor 251 may map data associated with currently-sensed interaction data from a single data source to a single routine-related feature. For example, feature preprocessor 251 may map currently-sensed and/or historically-sensed interaction data from a user messaging application, such as an email application, running on a specific user's smart phone or other device to a single routine-related feature. As examples, routine model trainer 245 uses the interaction data to determine the specific user regularly checks email on the specific device, or any device, in the morning.

In some implementations, feature preprocessor 251 may map data associated with currently-sensed interaction data from a plurality of data sources to a single routine-related feature. For example, feature preprocessor 251 may map currently-sensed interaction data from a website hosted by a remote server with which a specific user is interacting and a user device the specific user is using to interact with the website to a single-related feature. In this example, the descriptive data may be in the form of a device identifier associated with interaction data received from a user device. Routine model trainer 245 could determine, in this example, that the specific user visits an email provider website on a tablet computing device prior to bedtime. Interaction data collected from the same email provider website may not be used to infer the specific user's bedtime routine if the specific user interacts with the email provider website on a smart phone while getting ready for work in the morning.

Inferential evaluator 253 may be configured to extract contextual data from sensed interaction data and provide the extracted contextual data to storage 220 for use by other components of system 200. Contextual data, in general, can correspond to any information providing context to any interaction data utilized by system 200 by describing circumstances surrounding users, devices, and/or applications when interaction data is acquired. Contextual data can provide background information for sensed interaction data that enables system 200 to identify more patterns within interaction datasets 233 than would otherwise possible if system 200 was unaware of the surrounding circumstances.

Examples of contextual data include: tasks being performed at the time, such as military reserve training, trying to lose weight resulting in users waking up earlier to jog; information regarding temporal significance such as birthdays, holidays, anniversaries, seasons of the year, special events, vacations, associations between recent events; information regarding geographical significance, such as work place/home locations, changes in location (e.g. moving from one city to another city or one time zone to another time zone), vacation destinations; or any other information that provides system with a higher level of understanding about circumstances surrounding sensed interaction data.

Data analysis component 255 is generally configured to implement routine-related logic provided by routine model engine 240 in user routine models on routine-related features comprised of data associated with interaction data from feature preprocessor 251. By implementing routine-related logic on routine-related features, data analysis component 255 is able to determine routine-related inferences and the various metrics, scores, or statistical information associated with routine-related inferences, such as confidence scores, variance metrics, central tendency values, probability distribution functions, and the like. In cooperation with storage 220, data analysis component 255 may be further configured to update (or initialize) routine-related profiles associated with the specific user using routine-related inferences and the various metrics, scores, or statistical information associated with routine-related inferences determined from currently-sensed interaction data.

Outlier detector 257 may be configured to identify routine-related inferences deviating from previously determined routine-related inferences enough to constitute a statistical outlier (“outlier inferences”) using a pre-determined cutoff. For example, the pre-determined cutoff may be established according to known statistical anomaly detection methods, such as: Fuzzy Logic based outlier detection; Cluster Analysis based outlier detection; Density-based techniques, or any other known statistical anomaly detection metric. In some implementations, outlier detector 257 compares routine-related inferences with previously determined routine-related inferences associated with particular routine-related profiles using a pre-determined cutoff.

In some implementations, data associated with routine-related inferences are identified as statistical outliers by outlier detector 257 and are stored in interaction datasets referred to herein as “outlier datasets.” Such data, for example, may include the determined routine-related inference, any routine-related features used to determine that routine-related inference, or any currently-sensed interaction data acquired within a specified time of determining that routine-related inference. In some implementations, outlier datasets are used to train user routine models according to any of the implementations disclosed herein. In these implementations, outlier datasets may be used instead of and to replace a portion of and/or be merged with interaction datasets in training user routine models that are referred to herein as “alternative user routine models.” In some implementations, routine-related inferences determined using alternative user routine models are used to generate routine related profiles (referred to herein as “alternative routine-related profiles”). In these implementations, alternative routine-related profiles may be identified using alternative profile labels based on some commonality within datasets used to train their respective alternative user routine model, as determined by routine model engine 240.

For example, if routine model engine 240 determines that an outlier dataset used to train an alternative user routine model is comprised of interaction data associated with a particular geographic location (e.g. Israel, Europe, a vacation home in Mexico, etc.). In this example, an alternative routine-related profile generated using routine-related inferences determined using this alternative user routine model may be identified using an alternative profile label designating the particular geographic location. Accordingly, the alternative routine-related profile of this example may comprise routine-related aspects for the specific user that are specific to that particular geographic location. For example, the specific user may check email in the morning when vacationing in Mexico compared to at night when they are home working.

As another example, a routine model engine 240 determines that an outlier dataset used to train an alternative user routine model is comprised of interaction data associated with a particular period of time (e.g. weekdays/weekends, summer/winter, specific weekends every month, etc.). In this example, an alternative routine-related profile generated using routine-related inferences determined using this alternative user routine model may be identified using an alternative profile label designating the particular period of time. Accordingly, the alternative routine-related profile of this example may comprise routine-related aspects for the specific user that are specific to that particular period of time. For example, the specific user may be in a military reserve unit, which results in the specific user checking email earlier on specific weekends of the month they are training with the military reserve unit versus when they are at home relaxing on the weekend.

Recommendation engine 260 is configured to receive requests for user attribute data, such as routine-related aspects for a specific user, identify the requested user attribute data, optionally using routine-related profiles associated with the specific user, and provide the identified user attribute data to an application, service, or device submitting the request. In some implementations, recommendation engine 260 may be implemented as an application programming interface (“API”). As shown in FIG. 2, recommendation engine 260 is comprised of client-side service interface 261, server-side service interface 263, and/or cloud-based service interface 265.

Client-side service interface 261 is configured to receive requests from client-side recommendation applications or services that directly provide time-sensitive recommendations to a specific user. As an example, received requests could originate from an application running on the specific user's smart phone, such as a personal assistant application, a communication application, or an email application. In another example, a request could originate from a controller communicatively coupled to an actuator associated with any client-side device, machine, or appliance having automation capabilities used by the specific user.

Server-side service interface 263 is configured to receive requests from server-side applications or services that may be hosted on 3^(rd) party devices that provide recommendations to users. For example, the received request could originate from a server hosting a website offering commercial or informational services related to social media, traffic, weather, news, and the like. In some implementations, requests could be received from a recommendation engine associated with a routine inference engine in association with another user (e.g., the specific user's family members, friends, etc.). Similarly, cloud-based service interface 265 is configured to receive requests from any cloud-based applications or services.

A routine-related prediction or inference of a routine-related aspect for a specific user may optionally be determined using currently-sensed and/or historically-sensed interaction data and one or more user routine models trained using previously-sensed interaction data. An interaction dataset may be populated using previously-sensed interaction data. Previously-sensed interaction data can be received from an interaction data collection component (e.g., data collection component 215 of FIG. 2) prior to being accumulated in stored datasets. In some cases, previously-sensed interaction data is retrieved from stored datasets that include any of the interaction data described with respect to data collection component 215. For example, stored datasets may include accumulated previously-sensed interaction data associated with a specific user from an individual dataset. In another example, stored datasets may include accumulated previously-sensed interaction data associated with a plurality of users from a crowd-sourced dataset. In another example, stored datasets may include accumulated previously-sensed interaction data from an individual dataset, a crowd-sourced dataset, or a combination thereof.

In implementations using crowd-sourced datasets, pre-processing may be performed on previously-sensed interaction data retrieved from crowd-sourced datasets prior to populating interaction datasets. Such pre-processing may include noise filtering, removal of outlier data, and/or treatment of missing data. In implementations with crowd-soured datasets, pre-processing may include filtering previously-sensed interaction data from crowd-soured datasets using one or more filters based on user attributes (e.g., user attribute data 231 of FIG. 2). When used, the one or more filters segregate previously-sensed interaction data received from users with the user attributes from previously-sensed interaction data received from users without the user attributes. Consequently, filtered previously-sensed interaction data may be either included or excluded from the interaction dataset to provide previously-sensed interaction data that is generally tailored for training, testing, and/or validating user routine models.

The user routine model may be trained, tested, and/or validated using populated interaction datasets. As discussed above, user routine models are trained using any known machine learning technique by identifying one or more routine-related features in the interaction dataset. In some implementations, routine-related profiles for the specific user are generated by populating the routine-related profiles with initial values determined using previously-sensed interaction data in populated interaction datasets. In these implementations, confidence scores associated with such routine-related profiles are assigned a minimal value (e.g. zero, 1%, 0.02, etc.). For example, a routine-related profile for the specific user may be generated by populating the routine-related profile with initial values for routine-related aspects. Alternatively, the initial values for routine-related aspects in this example may be assigned confidence scores using any numbering system or combinations thereof.

User routine models include routine-related logic that defines a logical framework for determining routine-related inferences through evaluation of data associated with currently-sensed interaction data. In some implementations, routine-related logic includes one or more of the following probabilistic rule types: prediction rules, ranking rules, clustering rules, or classifying rules. Routine-related logic defines the logical framework by: mapping data associated with currently-sensed interaction data to each of the one or more routine-related features; prescribing relationships between the one or more routine-related features to determine routine-related inferences using data associated with currently-sensed interaction data; and, in some implementations, assigning routine-related weights to at least one routine-related feature. Routine-related weights are assigned to particular routine-related features based on a particular routine-feature's relative significance in determining (e.g. predicting the likelihood of) a routine-related inference. As such, user routine models and their determined routine-related inferences may be used to generate or update routine-related profiles for a specific user.

Currently-sensed interaction data can be received via one or more sensors associated with user devices and a routine-related inference can be determined through evaluation of data associated with that currently-sensed interaction data according to routine-related logic associated with the user routine model. In implementations, data associated with that currently-sensed interaction data includes one or more of the following: raw interaction data received from sensors, descriptive information associated with the raw interaction data, inference data determined from raw interaction data and/or descriptive information, or any combination thereof. As discussed in connection with routine inference engine 250 of FIG. 2, in implementations, routine-related inferences may be presented in various formats depending on type of routine-related logic used to determine a particular routine-related inference, such as classification labels, probability distribution functions, expected outcomes, outcome scores, and the like.

A routine-related profile for a specific user can be updated or initialized using the routine-related inference. In implementations where routine-related profile(s) have not been generated with initial values, routine-related inferences may be used as initial values to initialize the routine-related profile(s). In implementations where routine-related profiles are generated by populating the routine-related profile(s) with initial values determined using previously-sensed interaction data in populated interaction datasets, routine-related inferences may be reconciled with corresponding initial values. In these implementations, routine-related inferences are reconciled with corresponding initial values through replacement, averaging, weighted averaging, interpolation, extrapolation, and the like. In these implementations where confidence scores are assigned, confidence scores may be increased from previous values according to any of the implementations described herein.

One or more routine-related aspects may be provided for a specific user where a request is received for the one or more routine-related aspects for the specific user. The one or more routine-related aspects can be identified using routine-related profiles associated with the specific user, in response to receiving the request. The routine-related profiles being generated using interaction data according to any of the implementations described herein, such as described above. Further details of generating routine-related profiles are provided in connection with routine inference engine 250 of FIG. 2. The one or more routine-related aspects can be provided to the device, application, or service submitting the request.

Automated Action Item Tracking and Notification System

Having described an optional system and various methods for generating routine-related aspects of routines of users and/or querying user attribute data, in accordance with some implementations of the present disclosure, FIG. 3 is a diagram depicting an exemplary system 300 for tracking action items in user messages of users, in accordance with implementations of the present disclosure. In some cases, system 300 and system 200 are subsystems of the same system. In other cases, the system comprises system 300 along with an alternative to or variation of system 200.

By way of example, system 300 includes action item engine 366, one or more user messages, such as user messages 382, network 110 or a different network, storage 380, which in some implementations corresponds to storage 220 of FIG. 2, and presentation component 398. It is noted that while the present disclosure while describes emails as example of user messages, the disclosure should be interpreted as being directed to, when applicable, user generated computer messages in general, and not only emails. Thus, the description can apply to text messages, phone calls, voice messages, device messages, instant messages, or other types of user generated computer messages.

As an overview, action item engine 366 is configured to analyze and track user messages that are sent by a user and received by a user and/or action items extracted therefrom. In doing so, action item engine 366 can leverage routine-related aspects of the user, which may be determined in conjunction with one or more instances of system 200 of FIG. 2, as described above and/or other routine tracking and analyzing system. The analysis can include extracting message attributes from user messages and/or data associated with the user messages using action item extractor 366A. Examples of message attributes include message attributes 388. Other examples of message attributes include action items, such as action items 320.

Action item engine 366 can utilize the message attributes along with other data associated with the user to determine one or more actions to take on the user's user messages and/or action items. This can include determining which action to take for an action item (e.g., provide a notification, forward a user message to a user associated with the user, etc.), such as by selecting the action from a group of predetermined actions, and/or determining at least one parameter of the action item, such as a message to provide to the user in the action (e.g., notification), a time to present a notification corresponding to the action item, or whether to present a notification corresponding to the action item. Each of these determinations can utilize a dedicated machine learning model that makes the determinations based on features provided to the model, or any combination of these determinations can be combined into a single machine learning model.

Action manager 366B generates and updates the actions, such as notifications to parties regarding action items, which can be about sent or received user messages, even where or because one or more particular users has already opened and/or read the user messages. Action router 366D provides the generated actions to presentation component 398 for display to the designated parties or users which may be determined by action manager 366B. Notification 399 is one such example of a notification. Typically the notifications specify, identify, or describe, the one or more action items the notifications are about, as will later be described in further detail.

The actions may include providing a notification to the user and/or at least one other user regarding an action item. Action router 366D works in conjunction with presentation component 398 to present and display notifications provided by action item engine 366 to users. A notification can be provided to the user passively or actively and can comprise a user message the notification is regarding, a link to the user message, an identifier of the user message, a new user message generated for the notification, a text message, a computer generated message, push notification, a pop-up notification, and the like.

Another example of a notification is a flag state or state indicator. For example, action router 366D could set a state of a user message based on a detected status of the user message. The flag state indicator could correspond to and indicate to the user the state of the user message, amongst a plurality of potential states that action router 366D can set. Examples of states are those based on the analysis of action items, such as completion criteria of those action items, due date of those action items, and the like. Another example is whether the user read the user message. Whether the user has read the user message may be inferred as described elsewhere herein, and the system can determine that an opened user message was not read, or not sufficiently read or otherwise addressed by the user. An example of a state indicator is a colored icon, where different states are represented by different icons. Another example of a state indicator is a status message, where different states are represented by different status messages that may be generated from templates (e.g., “This message has not been responded to,” “You last opened this message on Jun. 28, 2016,” “You have an outstanding response for this message” etc.). The state indicators can be presented in association with the user messages, such as in a message center of an user message application that lists a user's user messages and allows access to individual user messages from the list. A state indicator could be presented in-line with its corresponding user message or user messages. It is noted that a single user message could have multiple notifications and they may be presented to the user concurrently and/or at different times.

An example of a notification is a reminder of a user message sent by the user or received by the user (i.e., a reminder notification). In some cases, the notification is based on whether the user message has been responded to, either by the user or at least one other user. In some cases, the notification corresponds to automatically forwarding or suggesting forwarding of the user message to at least one other user. In some respects, the notification can be based on the user opening and/or reading the user message, or at least one user message associated with the user message, and context surrounding the opening and/or reading of the user message or at least one user message associated with the user message. Thus, a single notification may be based on many user interactions with or associated with at least one user message over an extended period of time. Further, the notification may be updated based on these interactions using action item updater 366C and/or feedback analyzer 350D, such as when completion criteria and/or parameters of an action item(s) should be updated.

Also, action items and/or notifications can be based on user interactions associated with user messages from any number of users associated with the user messages. Thus, at least some of the user interactions described herein could be by a different user than the user that receives the notification. Furthermore, at least one of those users may not be a sender or recipient of user message the notification concerns. As examples, the system may identify the user from text of the message body and/or an attachment to the user message, based on another user (e.g., a send or recipient of the user message) forwarding the user message to the user, or otherwise based on the user being associated with another user (e.g., a known assistant, coworker, boss, etc.). The user could be identified in an organizational chart as being associated with the other user. Further at least some of the user interactions can be with user messages associated with the user message the notification is about. This can include user messages that are part of the same thread as the user message, forwarded versions of the user message, and/or user messages that reference the user message (whether an user message references another user message could be inferred based on an analysis of the text of the message body and/or attachments of one or both user messages).

As shown, messages 382 each comprise a header, a message body, and attributes of the message. For example, message 378 includes header 384, message body 386, and message attributes 388. In the present example, each of messages 382 is an email, by way of example. Any combination of this information may be embedded within the corresponding message and/or stored in association with the corresponding message. The header comprises header information corresponding to header fields of the message. The header information can comprise, for example, any information specified for header fields under a standard messaging format protocol, such as a Request for Comments (RFC) standard from the Internet Engineering Task Force (IETF) or the Internet Society (ISOC). As one example, the header fields can be any of those specified by RFC 5322. Examples of header fields include trace, resent-date, resent-from, resent-sender, resent-to, resent-cc, resent-bcc, resent-msg-id, orig-date, from, sender, reply-to, to, cc, bcc, message-id, in-reply-to, references, subject, comments, keywords, and the like. Where another messaging type is employed, such as a text message, different standards may be applicable.

The message body comprises the message provided and/or generated by a user in drafting the user message, such as message attachments or information within message attachments, message text, message images, message audio, and the like. The message body can comprise information typed in by the user, dragged and dropped in by the user, attached by the user, or otherwise included based on user interactions by the user while drafting the user message.

The message attributes, such as message attributes 388, comprise one or more attributes of the user message, or computer message, that are extracted based on the user message, such as information extracted from the user message, and/or context surrounding the user message, including context surrounding the sending and/or receiving of the user message and/or user messages associated with the user message, such as those belonging to a common user message thread or conversation. The message attributes can be extracted by action item engine 366, as will later be described in additional detail. Generally, message attributes correspond to semantic characteristics of user messages that are in a format usable by action item engine 366 to determine one or more actions regarding the user messages, such as to provide and/or generate notifications to or for users.

Action item engine 366 can employ a data collection component, such as data collection component 215 of FIG. 2, in order provide the information utilized to make any needed determinations and/or analysis related to user messages of users. To this effect, action item engine 366 includes action processor 350 comprising text processor 350A, interaction analyzer 350B, and feedback analyzer 350D, which can correspond to subcomponents of data collection component 215 or can supplement data collection component 215. Action item engine 366 can also employ a routine model engine and routine inference engine in order to facilitate determinations, analysis, and inferences based on routines of users, routine-related aspects of users, routine-related inferences, or other information derived from routines of users. To this effect, action processor 350 includes inference engine 350C which can employ or incorporate routine model engine 240, routine inference engine 250 of FIG. 2, and/or any of the various machine learning models described herein. Thus, inference engine 350C is capable of not only inferring routine-related aspects of users, such as those related to user messages, but also leveraging routine-related inferences to make inferences and determinations using inferred information. Thus, when the present disclosure describes inferences made with respect to system 300, in one approach, inference engine 350C can base those inferences on routine-related aspects of routines of users.

Text processor 350A is configured to analyze the text of user messages, such as any of the text from various parts of the computer messages including the message body of the user messages and the header of the user messages. Text processor 350A is capable of performing any combination of structured, semi-structured, and structured information extraction on the text of the user messages. In performing unstructured extraction, for example, text processor 350A can utilize natural language processing in order to interpret the text with respect to the user message. The extracted information can be mapped to message attributes and/or used to interpret user interactions (e.g., be mapped to features of machine learning models).

Interaction analyzer 350B is configured to analyze user interactions with respect to one or more particular user messages. The user interactions can be utilized to generate features of any of the various machine learning models described herein. Examples of user interactions that can be detected by interaction analyzer 350B include the user opening a user message, the user reading an user message, the user scrolling through the user message, the user saving a draft of a user message, the user sending a response to another user message related to the user message, opening a user message in the same thread or conversation as the user message, the user performing some action on a designated device or device type, such as a mobile device, mobile phone, desktop, or other device specified with respect to user devices 10, the user setting or removing a flag, category, or other metadata associated with the user message or a related user message, and the user performing any of the delineated actions with an user message associated with the user message. In some implementations, interaction analyzer 350B is capable of detecting user interactions cross device in association with respect to particular users. Thus, interaction analyzer 350B can be used to detect that a user is reading their user message at home on a home PC, and that the user later opened, but did not read their user message at work on a work laptop.

Feedback analyzer 350D is configured to analyze feedback from users, with respect to one or more particular user messages and/or action items. The user feedback can be utilized to generate features of any of the various machine learning models described herein. In some cases, feedback analyzer 350D extracts feedback data from user interaction data provided by interaction analyzer 350B. The feedback data can be based on feedback provided by the user in response to one or more actions generated by action manager 366B. In some cases, the feedback data is provided to inference engine 350C and action item updater 366C, which uses the feedback data to update routine models corresponding to action generation for the user and/or action item extraction and determination of parameters and completion criteria of action items for users. Examples of user feedback include detecting performance of or failure of performance of a predetermined user action after, in response to, or based on a notification presented for a user message, such as the user responding to the user message. Other examples include user responses to questions or prompts presented to the user regarding notifications or preferences thereof, user configurations or settings made to or updated for notifications, and the like.

At least some user feedback detected by feedback analyzer 350D can be explicit from the user. Other user feedback data detected by feedback analyzer 350D can be inferred from user interactions or information generated based on user interactions, such as information made available from text processor 350A. As an example, user feedback could be inferred from analyzing text of the user message or a user message associated with the user message. In some cases, feedback analyzer 350D determines that a user message corresponds to a response to the user message based on an analysis of the text.

Action manager 366B generates actions, such as notifications to parties about action items which may regard sent or received user messages, even where or because one or more particular users has already opened and/or read the user messages. In some cases, whether and/or a number of times the user has read or opened a user message corresponds to a feature in any of the various machine learning models described herein. Action router 366D provides the generated actions to presentation component 398 for display to the designated parties or users. Notification 399 is one such example of a notification. Notification may specify, identify, or describe, the one or more user messages the notifications are about, such as a message portion of the notification. Message 399B is an example of a message portion generated by action manager 366B for notification 399. Notifications may be generated base action manager 366B for user messages from any combination of accounts associated with the user (e.g., a single notification could be for an user message from one user message account and an user message from another user message account). Also, the generation can be based on interferences made based on user interactions with user messages that are tracked across multiple accounts associated with the user (e.g., any of the exemplary user accounts described herein).

In various implementations, action manager 366B generates notifications to a user about action items from received user messages of the user, even where or because the user has already opened and/or read the user messages. As examples, Action manager 366B can base notifications for a user message on any combination of determining whether the user has responded to the user message, determining when the user should respond to the user message, and determining when the user should be notified to respond to the user message. In some cases, action manager 366B determines a notification time for the user message and provides the notification to the user at or based on the notification time. For example, action manager 366B has assigned notification time 399A to notification 399.

In addition to or instead of the notifications being about action items for received user messages, in various implementations, action manager 366B generates notifications to a user about action items for sent user messages, or user messages that the user has previously sent to at least one recipient. As examples, action manager 366B can base notifications for action items on any combination of determining whether one or more recipients have responded to the user message, determining when one or more recipients should respond to the user message, and determining when the user should be notified regarding ones or more responses to the user message. In some cases, Action manager 366B determines a notification time for the user message and provides a notification to the user at or based on the notification time.

It is noted that disclosure herein regarding notifications to a user and determinations related to the notifications should be interpreted as being directed to, when applicable, action items for user messages that are both sent and received by the user. Furthermore determinations described with respect to the user that receives a notification about a user message, such as those used in order to make the determinations regarding the notification, should be interpreted, when applicable, as being directed to one or more senders of user message, and/or receivers of the user message, regardless of whether that party is the user.

In order to generate and determine aspects of a notification for an action item, action manager 366B can analyze and interpret various data associated with user messages. This can include message attributes 388 extracted by action item extractor 366A, various user interactions, and/or historical data, such as routine-related aspects.

In some respects, action item extractor 366A analyzes user messages, such as user messages 382, using text processor 350A, interaction analyzer 350B, and inference engine 350C to extract message attributes, such as message attributes 388 and action items 320. As mentioned above, message attributes of a user message, or computer message, are extracted by action item extractor 366A based on the user message, such as information extracted from the user message, and/or context surrounding the user message, including context surrounding the sending and/or receiving of the user message and/or user messages associated with the user message, such as those belonging to a common user message thread or conversation. It is noted that message attributes may be extracted from more than one user message. For example, a single action item could have completion criteria and/or parameters extracted from multiple user messages.

Message attributes may be extracted from the text, or message body of the user message, such as portions of a user message drafted by a user. Message attributes may in addition or instead be inferred based on user interactions and/or extracted text from user messages. In some cases, at least some message attributes are extracted from the user message or a user message associated with the user message using structured, semi-structured, and structured information extraction to identify the message attributes from the text of the user message or an associated user message. Further, at least some message attributes for a user message may be based on at least one message attribute of at least one associated user message. For example, action item extractor 366A may identify or infer that the text of the user message refers to at least one other user message. Based on detecting the reference to another user message, action item extractor 366A can utilize one or more message attributes of the other user message or other extract a message attribute for the user message based on the message attribute of the other user message.

Examples of message attributes that can be extracted by action item extractor 366A include a length of the message body (e.g., the text thereof), number of attachments, specified senders of the user message, specified receivers of the user message, whether the user message is part of a thread, related user messages, action items and/or or parameters thereof. An action item corresponds to a task to be completed by a user based on a user message. A timing attribute corresponds to a timing assigned to an action item or action items associated with a user message.

FIG. 3 shows action items 320 as examples of action items extracted from user messages 382. Any number of action items 320 can be extracted from one or more of user messages 382. As shown, action item 322 includes completion criteria 324 and parameter 326. Each action item can include any number of completion criteria which can include any number of parameters.

Examples of action items or tasks represented by action item attributes include for a user to respond to the user message, for a user to respond to the user message with designated content attached and/or included in the message body of a user message or other computer message, for the user to respond to another designated user, for the user to forward the user message, for the user to text or call a user, or any suitable combination thereof. A user assigned to a task can be any user involved in a user message exchange or a user associated with one of those users. Thus, the user assigned to a task could be the user that receives the notification or a different user. In some cases, multiple action items are extracted from a single user message. Any user may be assigned to any of the various actions items. In extracting an action item, action item extractor 366A may also extract or determine the user or users assigned to the action item. In some cases, one or more users or other parameters of completion criteria may be assigned to or associated with the action item by default, such as the sender or receiver of the user message.

Furthermore, for a task for a user that is with respect to another user, the other user can be specified in the action item as one or more particular users, types of users, or as any user. In some cases, the other user may be implicit from the type of action item assigned to the message attribute. For example, certain action items may by definition be with respect to a type of user. Examples of types of users include a sender of the user message, a recipient of the user message, a boss, assistance, manager, or user having some other particular relationship to a user. In some cases, a relationship to a user can be extracted from a relationship chart that includes the user or that the user can be mapped to. As an example, storage 380 can include an organizational chart that includes or can be used to identify relationships between users. The organizational chart can be user defined and/or inferred from user messages between users.

In some approaches, action item extractor 366A determining action items of action item attributes comprises mapping user message(s) to one or more action item templates. Action item extractor 366A can determine whether the user message(s) corresponds to one or more of the action item templates based on an analysis of the user message or other information associated with the user message. For example, action item extractor 366A can determine whether one or more of the action items apply to the user message based on an analysis of the text of the user message by leveraging text processor 350A. A template for an action item can include one or more completion criteria.

As used herein, completion criteria correspond to criteria utilized to determine whether an action item is completed, or satisfied. Action manager 366B can refrain from providing a notification for an action item and/or user message based on determining that all of the completion criteria are satisfied. As another example, a message of a notification can indicate which of the completion criteria are satisfied and/or not satisfied when not of the completion criteria have been satisfied. As a further example, the action selected by action manager 366B can be based on completion criteria in the subset of the completion criteria that has not yet been satisfied.

Action manager 366B can determine whether completion criteria has been satisfied by analyzing sent and/or received user messages of the user, including the text, attachments, subject, or any other features thereof. In some cases, message attributes are extracted from these user messages and analyzed with respect to the completion criteria to determine whether any of the completion criteria is satisfied. The message attributes can be extracted similar to other message attributes described herein, and can comprise similar information. It is not that action manager 366B may also analyzer sent and/or received messages of the user other than user messages. For example, action manager 366B may analyze computer messages on different messaging platforms, such as instant messages, phone calls, social network messages, and the like to determine whether one or more completion criteria has been satisfied. Thus, a user may respond to a user message over instant message and action manager 366B refrains from generating and/or providing a notification of a corresponding action item based on identifying the response.

Action item extractor 366A can map text in the user message and/or an associated user message to parameters of action item templates (e.g., after determining an action item template applies or as part of the determination). Parameters of an action item can correspond to variable information used by action manager 366B to determine whether the action has been completed or satisfied (e.g., whether completion criteria of the action item is satisfied). In some cases, parameters can be predefined, such as in an action item template. Further, in some cases, completion criteria include one or more of the parameters. For example, a completion criteria of the user sending a user message to a particular party may use the particular party as a parameter. A message attribute, such as the sender of the user message may be mapped to the parameter of the completion criteria.

Parameters of an action item can include the users or types of users the task is with respect to (e.g., which specified performing user or users is the party that completes or performs the task and in some cases, which specified non-performing user or users are part of the task such as a recipient of information).

Other examples of parameters of an action item include content types or categories that are part of the task. A content type can correspond to a particular type of document, such as a spreadsheet, word processing document, image file, web page, or other document type. In some cases, a content type may correspond to a particular file extension or set of file extensions. A content type can also correspond to topical content of content, such as whether the content covers sports, weather, the news, work, a report or project, finances, scheduling, an event, and the like.

In determining whether a content type of an action item is satisfied, action manager 366B can, for example, analyze attachments to user messages, such as filenames, file extensions, and/or content contained therein. Action manager 366B can also analyze the text portion of drafted user messages.

Examples of timing attributes include a deadline, due date, a time frame, a time line, or other temporal or timing information for performance of one or more particular action items. In some cases, one or more action items have default or preconfigured timing attributes that are used when the action item is assigned to the user message. For example, these timings may be defined for an action item relative to other message attributes (e.g., temporal attributes), such as relative to the send date of the user message, the receive date of the user message, the date the user message was received, opened, or read the date the user message was first or last received, opened, or read, the forwarding date of the user message, and more.

In some cases, using text processor 350A, for example, action item extractor 366A extracts at least one timing attribute of at least one action item from a user message. This can include a deadline to respond to the user message, a due date for a response to the user message, or a time frame for a response to the user message. The temporal information may be specified by the drafter of the user message, either explicitly or implicitly. For example, action item extractor 366A can infer or interpret the message attributes based on the natural language processing of the text. As one example, the text of the user message could include relative language such as “Send me this report next Tuesday,” and the timing attribute can be set to the following Tuesday from when the message was sent as specified in the message attributes.

As another example, the text could include “Send me this report after you send me the other report.” In this case, action item extractor 366A may have knowledge of the other report from another user message or other tracked interactions between the sender and receiver of the current user message. Furthermore, action item extractor 366A may set the temporal attribute as a time that is relative to completion of another detectable action by action manager 366B. The timing attribute may then be based on action manager 366B determining the completion criteria of the related action item or action is complete. As a further example, the text could include “Send me this report with the other report I sent you.” In this case, a user message regarding sending the other report may specify the timing with the user message as a timing attribute of an action item corresponding to the sending the other report. Action item extractor 366A could infer that the temporal attribute associated with the other user message also be applied to the current user message and assigned that message attribute accordingly. Further, the completion criteria of the current user message may include that the user provide the other report (e.g., incorporate completion criteria from the other action item or merge the action items).

The amount of time used as a timing attribute of an action item can be machine learned, such as using routine model engine 240. For example, inference engine 350C can learn timings based on when the user typically performs or completes the task associated with the action item and/or prefers to perform or complete the task associated with the action item. Thus, for example, inference engine 350C can learn that the user typically responds to user messages on Monday mornings and use the time frame or a time derived therefrom as the timing attribute for the action item.

As mentioned above, action manager 366B can determine a notification time, such as time 399A for a notification. Determining a notification time can comprise determining whether to present, display, and/or perform some action with respect to a generated notification. Determining a notification time can also include determining or calculating a particular time to display or present a notification. The notification time is used to determine when the notification will be presented to a user. For example, action router 366D can use the notification time to determine when the notification should be sent to the user, or a user device associated with the user. As an example, the notification time can correspond to a time to send out a computer message comprising the notification to a user account associated with a particular user, and can be an user message, mobile operating system, or text message. As another example, presentation component 398 can present the notification to a user at or based on the notification time. For example, the notification time may be sent to a user device any time after being generated and be displayed at or based on the notification time. In some cases, the notification time is determined on the user device, for example, where one or more portions of action item engine 366 are incorporated into the user device.

Action manager 366B can determine the notification time based on one or more timing attributes of one or more action items of one or more user messages. For example, where a timing attribute of an action item is a deadline, action manager 366B can calculate the notification time based on the deadline. This can include calculating the notification time to be a predetermined about of time before the deadline.

Where multiple action items have been detected for a user message, the notification time may be based on the earliest of the notification times and the message of the notification may concern each notification. As another example, action manager 366B can generate multiple notifications for a single user message. Each notification can correspond to one or more of the action items. Thus, each action item could have a corresponding notification and notification time based on the timing attribute of the notification. Furthermore, action manager 366B could group one or more action items together based on parameters or features between the action items.

It is further contemplated that a single notification could correspond to multiple user messages. For example, action manager 366B could identify action items from multiple user messages based on the parameters or features of the action items. As an example, in some implementations, action manager 366B groups action items together for a notification based on identifying at least one corresponding message attribute of the action items and/or user messages corresponding to the action items. For example, action items could be grouped together based on having a common sender, recipient, and/or any of the various message attributes described herein.

In some cases, the grouping is based on the timing attributes and/or notification times assigned to the action items, such as based on identifying a proximity between the timing attributes and/or notification times of the action items. Action items that each have timing attributes or notification times within thirty minutes of each other or some other designated time frame could be grouped together. The notification may identify each user message corresponding to the notification. By grouping action items together, the number of notifications needed for the action items is reduced. Grouping action items reduces bandwidth and power needed to transmit notifications, processing in generating notifications, and efficiency of the user in that the user has fewer notifications to manage and/or view.

Timing attributes of action items can be used as notification times, or notification times can be calculated or determined from timing attributes. In some cases, notification times are machine learned, such as using routine model engine 240. For example, inference engine 350C can learn timings based on historical notifications sent or provided to the user. For example, using feedback analyzer 350D, inference engine 350C can compare a time of a notification of an action item with when the user actually performed or completed the task corresponding to the action item. Feedback analyzer 350D can update the machine learning model based on the difference between the timings. Using this approach, action manager 366B can present notifications at times that the user is more likely to respond to the notifications. For example, inference engine 350C may learn that the user is more likely to respond to a notification presented thirty minutes before a due date then an hour before the due date. As another example, inference engine 350C may infer that the user is likely to respond to notifications in the evening.

In some cases, feedback analyzer 350D maintains a distribution (e.g., sine or probability distribution) based on time stamps of events of a routine of the user, where the event corresponds to historical notifications of action items. Sensitivity analysis can be applied to the time stamps to determine a notification time where the user is at least more likely than not to respond to a notification. In some cases, a notification time may be generated to be earlier or later than an optimal time calculated from historical data to facilitate tuning of the sensitivity analysis.

Action manager 366B can determine action items, whether completion criteria of action items are or are not satisfied (e.g., to evaluate parameters), timing attributes, notification times, actions, and/or messages of notifications for user messages based on identifying and/or determining user context of a user. As another example, action manager 366B can determine priorities of notifications, action items, and/or user messages with respect to one another to select from which subset to surface, and/or rankings of surfaced user messages, action items, and/or notifications.

User context can be determined based on currently-sensed interaction data and historically-sensed interaction data, such as using and inference engine 350C and/or interaction analyzer 350B (e.g., whether to present a notification or a particular time to present a notification). User context can comprise one or more activities inference engine 350C determines the user is currently engaged in or will be engaged in. Thus, action manager 366B can determine a notification time for a notification based on inference engine 350C determining the user is or will be engaged in one or more predefined activities.

In some cases, activities are determined independently of routines tracked for the user. For example, where user interactions indicate the user has loaded a user message application and looked through multiple user messages, inference engine 350C can infer the user is reading user messages. In other cases, activities are part of routines, such as routine-related aspects or events of one or more routines and inference engine 350C determines that the user is currently engaged in or will be engaged in the activity based on the routine-related aspects and/or user interactions which may indicate the user is or will participate in the activities. For example, the user may have a tracked routine of checking emails every afternoon. Based on the user loading an email application, the tracked routine, and the time associated with the routine, inference engine 350C can infer that the user will be reading emails as part of the routine.

As a further example, based on routine-related aspects of the routine, inference engine 350C may identify that the user typically practices the routine of responding to emails early in the morning at work. Based on the identification, the notification time for one or more notifications may be generated, for example, to be within the time frame indicated by the interaction dataset of the routine that the user typically practices the routine. As another example, inference engine 350C can determine that the user typically drives to work between 7:00 AM and 8:00 AM and refrain from presenting the notification during that time frame based on the determination.

In some implementations, timing attributes and/or notification times are based on determining whether the user has opened and/or read a user message regarding a notification(s). In some cases, action manager 366B determines that the user has read and/or opened the user message. This can include, for example, identifying metadata assigned to the user message that indicates the user has opened the user message. As another example, action manager 366B can determine that the user has not read the user message even where the user message has been opened based on user context determined by action manager 366B. For example, the interaction data can be compared to one or more parameters of completion criteria of a corresponding action item. These determination may be based on determining and/or identify user context regarding (e.g., during) the opening and/or reading of the user message. For example, action manager 366B can analyze user interaction data using interaction analyzer 350B to determine whether the user read the user message.

Factors that the determination can be based on include scroll time of a window comprising a message of the user message, time spent with the user message opened, a number of times the user opened the user message, whether the user opened and/or viewed one or more attachments, and the like. Other factors include which device type, or particular device the user was using to open or view the user message, such as whether the device is a mobile device, a phone, a laptop, or other type of device specified with respect to user device 102 a, or which account type, or particular account the user was logged into when interacting with the user message.

Further factors include determining and/or identifying any of various user message characteristics, such as particular message attributes and/or predetermined message attribute types, whether the user message includes an attachment(s), a type of attachment(s), a length of the text in the message of the user message, and the like, a type of content included in an attachment and/or message of the user message, and the like.

Additional factors correspond to whether the user is engaged in or will be engaged in at least one routine that is modeled by one or more user routine models. For example, if inference engine 350C determines the user is driving to work, the user is likely not focused on reading user messages. Therefore, the notification time may be based on that determination. The activity of the user (e.g., driving to work, the user attempting to delete a user message that includes an action item that does not have its completion criteria satisfied) can be determined based on the routine and the notification time of the user message may be based on the activity derived from the routine. In other cases, the activity is determined independently from user routine models (e.g., by analyzing user interaction data). Further factors include whether the user has printed the attachments of the user message, spent greater than a threshold amount of time viewing the user message, or other factors indicating whether the user is focused on the user message.

Using the forgoing factors and determinations, for example, action manager 366B can determine that an action item still requires action. For example, a user message still may require a user's attention even after having been opened. The user may have opened the user message on a mobile device while driving. An action item extracted from the user message may correspond to the user signing documents attached to the user message. Based on determining that the user has not opened the attachment and viewed the user message while driving, action manager 366B can determine that a notification should be provided to the user. As another example, from historical observations and routines of the user, inference engine 350C can determine that the user is unable to complete the action item on the mobile device and/or at a certain location. For example, the user may need to use a work computer to print documents for signature. Thus, the inference engine 350C can infer one or more completion criteria of the action item are unsatisfied.

Timing attributes, action items, completion criteria and/or parameters thereof, notification times, actions, and/or messages of notifications can also be based on historical response patterns to action items and/or user messages based on user message context. For example, inference engine 350C can learn that the user typically responds quickly or requires responses quickly for user messages with specific senders or receivers such as user messages from a boss, a family member, a co-worker, an assistant or other type of user or specific user. Therefore, notifications for action items for user messages involving these parties may have shorter notification times than other user messages. For example, action manager 366B can generate a time for a notification based on a timing attribute of an action item, such as a due date, by factoring in the user message context. This user message context can be from the message attributes of the user message. For example, action manager 366B can utilize at least one message attribute of user messages to learn at least one routine-related weight for at least one routine-related feature by analyzing interaction datasets 233 used to train user routine models 235. To generate a notification time for a particular user message, the routine-related features can be extracted from the message attributes and applied to one or more user routine models. Any of the various other attributes determined herein can be similarly learned for users.

Referring now to FIG. 4, FIG. 4 depicts a flow diagram of method 400 for notifying users of action items, in accordance with implementations of the invention. At block 410, method 400 includes extracting completion criteria of an action item from a user message. For example, action item engine 366 can extract message attributes 388 from user message 378 based on the user having sent or received the user message, and can determine completion criteria of an action item, as well as parameters of the completion criteria from message attributes 388. It is noted, the action item could have previously been extracted from one or more other user messages, such as instant messages, and the like. As another example, the action item could be extracted from the user message along with the completion criteria and/or parameters of the completion criteria. In some cases, extracting completion criteria adds completion criteria to existing completion criteria for an action item, which may have been extracted from at least one other user message. Further, at least some of the completion criteria could be updated, such as by updating one or more parameters of the completion criteria. For example, the text of the user message could indicate a change to a due date or other modification. This can be determined using natural language processing or other extraction techniques.

At block 420, method 400 includes identifying a routine-related aspect generated from a user routine model of a user. For example, routine inference engine 250 can infer the user practices a routine based on a user routine model of the routine for the user. Based on determining the user practices the routine, the system can identify a routine-related aspect of the routine for the user. Routine inference engine 250 can generate the routine-related aspect from the user routine model of the user for the routine. In some cases, the routine-related aspect that is determined is based on the completion criteria of the action item. For example, the routine-related aspect and/or routine may be associated (e.g., assigned such as in an action item template) with one or more designated completion criteria and/or action items to be used to determine whether the completion criteria is satisfied and/or unsatisfied.

At block 430, method 400 includes inferring at least one of the completion criteria is unsatisfied based on the routine-related aspect and a parameter of the completion criteria. For example, action manager 366B can compare the routine-related aspect to at least one parameter of completion criteria to determine whether completion criterion is satisfied and/or unsatisfied. The comparison could be defined by a template for the completion criteria and/or action item, which specifies the routine-related aspect and/or the routine to be used in the comparison as well as conditions for when the completion criteria is satisfied based on the comparison. Although one routine and routine-related aspect is described, it should be appreciated that any number of them can be employed to determine whether a particular completion criteria is satisfied or unsatisfied. Further, in another variation, routines and routine-related aspects can similarly be used to infer or predict that the completion criteria will not be satisfied (e.g., the user will miss a due date), and a notification could be provide to a user based on this inference.

As an example of block 430, assume an action item is for a user to review a contract or other document. A routine-related aspect of a routine of the user for reviewing documents could be that the user typically takes a certain amount of time to review a document. Based on a comparison between interaction data generated by the user and the routine-related aspect, the system can determine that the completion criteria has not been satisfied. In other embodiments, the parameter is set based on the routine-related aspect of the user (e.g., a review time for the document based on the routine which may be adjusted based on document length and/or content). Attributes of interaction data generated by the user are compared to the parameter to determine whether the completion criteria has or has not been satisfied (e.g., the user was interacting with the document for significantly less than in a typical review and therefore the completion criteria is not satisfied).

At block 440, method 400 includes providing a notification to a user associated with the action item. For example, presentation component 398 can provide notification 399 to any user associated with the action item, such as a second or receiver of a user message (or completion criteria or parameter thereof) that corresponds to the action item, and/or an agent or other user associated with one of the foregoing users. In some cases, a notification time of the notification is determined based on user context and message attributes of one or more user messages corresponding to the action item. For example, action manager 366B can determine whether to display or present notification 399 to the user and/or time 399A to display or present the notification to the user based on the user content and message attributes 388. Action manager 366B can also select and/or generate message 399B based on similar information.

Referring now to FIG. 5, FIG. 5 depicts a flow diagram of method 500 for notifying users of action items, in accordance with implementations of the invention. At block 510, method 500 includes extracting an action item from a user message. For example, action item engine 366 can extract an action item from user message 378 using action item extractor 366A.

At block 520, method 500 includes determining an instance of the user practicing a routine. For example, routine inference engine 250 can determine a user associated with the action item practices a routine. Routine inference engine 250 can further determine an instance where the user is currently practicing will practice, or has practiced the routine based on the user routine model of the user for the routine. This can include comparing interaction data with one or more routine-related aspects generated from the user routine model.

At block 530, method 500 includes inferring completion criteria of the action item is unsatisfied based on the instance and a parameter of the completion criteria. For example, the interaction data can be compared to one or more parameters of completion criteria to determine whether the completion criteria has been satisfied.

At block 550, method 500 includes providing a notification to a user associated with the action item. For example, action manager 366B and/or presentation component 398 can provide notification 399 for display to the user based on time 399A.
